Hey Indus Valley, what's your tale
First planned drainage, without fail
3000 BC, baths so clean
Cities built with systems seen
Hey Mesopotamia, what's your way
Irrigation channels every day
Growing food in desert sand
Civilization's first great plan
Hey Roman Aqueduct, why so high
Bringing water through the sky
Lead pipes, fountains, baths galore
Engineering at its core
Hey Qanats, how do you flow
Persian tunnels down below
Moving water through the ground
Desert cities safe and sound
Water flowing, cities grow
Ancient wisdom still to show
Each system clever and new
Keeping people's dreams come true
Hey Storm Drains, why so deep
Keeping cities dry and neat
Victorian tunnels underground
Stopping floods from coming round
Hey Hoover Dam, why so strong
Holding Colorado's song
Power, water, flood control
Desert blooming, that's our goal
Hey Green Roofs, why plants up high
Catching rain drops from the sky
Slowing water's urban race
Giving nature back its place
Hey Bioswales, what's your role
Filtering water is our goal
Plants and soil working together,
Making cities handle weather
Some flows fast and some flows slow
Some cleaned quick and some cleaned slow
Each method special in its way
Managing water day by day
Hey Smart Sensors, what's your part
Making water systems smart
Real-time data flowing free
Stopping waste and leaks we see
Hey Water Future, what's ahead
Recycling systems widespread
Nature-based solutions grow
While digital watersheds flow
Water tech grows day by day
Finding new and better ways
What new systems will we see
As cities grow sustainably
Some systems old and some brand new
All helping water flow on through
Each innovation plays its part
Making cities water-smart
